THlLL-HCOUPLINGI.1

SPECIFICATION forming part of Letters Patent No. 609,477, dated August 23, 1898. Application filed October 6, 1897. Serial No. 654,231. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, CHARLIE Bron SroUeH, a citizen of the United States,residing at Creston, in the county of Union and State of Iowa, have invented certain new and useful Improvements in rPhill-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to certain new and useful improvements in thill-couplings, and relates more particularly to a form of coupling designed to insure a reliable union between the parts, as will be hereinafter fully specified,and illustrated in the accompanying drawings, made a part of this application.

The object, therefore, of my invention may be said to consist in providing; a safety appliance for carriages and other vehicles for which such a coupling is desirable.

In the accompanying drawings,Figure lis a perspective view of my invention complete, showing the several parts separated, ready to be assembled in their respective positions. Fig. 2 is a side view of my invention complete. Fig. 3 is a side View of the lockingbolt and rib. Fig. 4 is a sectional view taken on a line with the inner surface of one of the jaws of the clip.

Briefly stated, my invention consists in providing a peculiar form of locking-bolt and a reserve bolt and fa hook-like termination formed upon the iron connected to the shaft or pole. Y

Referring in detail to the several features involved in my invention, 1 is the clip employed to provide connection with the axle, and is constructed in the usual or any preferred way, while integrally formed with said clip or otherwise connected thereto are the vertically-disposed jaws 2 and 3, lying substantially parallel with each other and a sufficient distance apart to accommodate between them the usual tubular body 4, connected to` the shaft or pole in the usual manner, as by the integrally-formed flange or lip 5, designed to be bolted to said shaft or pole.

Integrally formed with thek tubular body 4 is the rearwardly downwardly extending hook-section 6, designed to partly encircle, yet lie out of contact with, the reserve bolt 7,

permanently secured at either end to the jaws 2 and 3.

The circular opening 8, extending through the tubular body 4, is provided near its upper side with the continuous recess or slot 9, while each of the jaws are provided near their forward ends with the circular openings 10, preferably of the same diameter as the opening 8.

Each of the openings 10 is provided upon its upper sidesand on line with each other with the slot or recess 1l, coinciding in size, but not in normal position, with the recess 9, formed in the opening 3, and it will be apparent that by sufficiently elevating the shaft or pole the recesses 9 and 11 may be brought into registration with each other, when the bolt 12 (more clearly shown in Figs. 1 and 3) may be placed in position, so that the rib 13 formed thereon will freely pass through the recess 11 and be received by the recess 9, when by lowering the shaft or pole, to which the tubular body is connected, the recess 9 will be moved downward out of registration with the recess l1, and thereby rotate the bolt 12 and bring therib 13 downward out of registration 'with the recess 11, resulting in reliably holding said bolt against longitudinal movement until the shaft or pole is again elevated. When the tubular body 4 is thus locked in position between the jaws by means of the bolt 12, the hook-section 6 is entirely out of ycontact with the reserve bolt 7, and the latter will not have any oice to perform until the bolt 12 is destroyed by wear, when the hook-section 6 will engage the bolt 7, and thereby insure against the serious results insually following the casual displacement of' the bolt employed to hold the parts in union.

In Figs. 2 and 4 I4 have shown the normal position of the hook and reserve bolt, and it will be readily apparent that the shaft or pole may be freely used in the usual manner without in any way interfering with said hook or bolt.

Having thus fully set forth the construc-a tion, advantages, and use of my improved coupling and safetyapplianca'what I claim as new, and desire to secure by Letters Pat ent, ism
